At the moment, the form used to search for players is fairly comprehensive and easy to use for cross-referencing several criteria.
But in my opinion, it would be great to add an additional search field, which would be the progression coefficient.
That would make it much easier to narrow down searches for young players.
Of course, I agree that for players aged 24 and over, there's no point as they all have the same coefficient, but for those who are still in training it would seem useful to me and would avoid sometimes having to consult the second page of dozens of players.

There's also a box for the number of training sessions (i.e. the number of points the player has) if I want to find players with at least 190 points.

It's getting ambitious xD
